Collegiate Trek Tumbler

The tapered base fit perfectly into my car's cup holder on the morning commute—no more coffee sloshing around the center console. The flip lid snapped shut tight, and I even tossed it in my bag with zero leaks.

The double wall insulation is no joke—my coffee stayed hot through a whole morning of classes and the commute. The flip lid seals tight enough that I tossed it in my backpack without a second thought, and both straws are a nice backup when I'm in the mood for something cold.

I was skeptical about the tapered shape fitting my car's cup holder, but it slides in perfectly and stays put on bumpy roads. The double-wall insulation keeps my coffee hot through back-to-back lectures, and the flip lid hasn't leaked once in my backpack.
